The set {1, pi, -3.9} is one such set.
4 belongs to any set that contains it. So {1, pi, 4, -37.5689, sqrt(2)} is a possible answer.
It is a set containing the single number, 3.14, a rational number. This must not be confused with the number pi, which is approximately 3.14 but is an irrational number.
Neative and it's a whole number, I think
It belongs to the interval (25, 27.3), or [-20.9, 10*pi], and infinitely more such intervals.It also belongs to the set of rational numbers, real numbers, complex numbers and quaternions.
Pi is both an irrational number and a transcendental number.
pi is a single number , not a set. Since it is not a set, it cannot have a subset.
No, pi is a set number.
If you're talking about real numbers, then it is an irrational number. Any number that cannot be written as a fraction is irrational. You cannot write pi as a fraction (22/7 is just an estimate). So any thing multiplied with pi cannot be rational either.
Pi is an Irrational number, which is one of the two subcategories of real numbers.
The set {1, pi, -3.9} is one such set.
what set is 0.56
It belongs to any subset which contains it. For example,the interval (3, 4){pi}{1, pi, 3/7}{27, sqrt(7), pi}
It belongs to any set which contains it. For example: {-21} {pi, yellow, -21, Germany} {numbers smaller than -17}
4 belongs to any set that contains it. So {1, pi, 4, -37.5689, sqrt(2)} is a possible answer.
Real, complex, quaternion, etc. But more specifically it's a transcendental real number, not being the root of an integer polynomial (and certainly not the ratio of two integers).
No. Pi is a set number, if it were negative (-3.14159...) it would not represent the ratio of radius to circumference.
